. To all whom it mag concern:

' gas meters is that the'bearing of the principal moving element of themeter is located in an inaccessible position so far as lubrication isconcerned, and an object of the present invention is to produce a simpleand elfective means for lubricating the universal joint or the bearingof the meter drum.

This, and other objects, which will be made apparent throughout thefurther de scription of the invention, are attained by the featuresherein described and illustrated.

I11 the drawings accompanying and forming a part hereof, Figure 1 is afragmental, sectional view of a meter equipped with my invention.

Fig. 2 is a sectional view of a gas delivery pedestal which forms adetail of the present invention.

Fig. 3 is a in Fig. 1.

Referring to the drawings, the apparatus illustrated is an ordinary formof wet gas meter. The drum 4 is inclosed within a casing 5, which formsa receptacle for the sealing liquid 6 of the drum. The casing isprovided with the usual gas outlet or delivery port and the drum isprovided with the usual means for successively connecting its separatechambers with the delivery and in,- let ports of the meter. The inletport 7 of the meter illustrated communicates with a passage 8, whichcommunicates with a gas passage formed in a pedestal 9. The pedesplanView of the pedestal shown tal 9 projects upwardly through the sealingliquid 6, and, as illustrated, forms a standard on which the universaljoint 10 of the drum 4 is mounted. The portion 13 of the pedestal, onwhich the joint 10 is mounted is located below the normal level of theliquid "WET-GAS-METER.

6.. For the purposezof providing gas passages ;through the sealingliquid and at the same time for providing means for introducinglubricant to the universal joint, Ihave so formed the pedestal that themaingas passage 11 communicates with one or more gas passages 12, whichare so arranged with relation to the supporting member 13 that sealingliquid surrounds and partially or wholly submerges the universal joint.In the illustrated embodiment the provided with four zles 9 each theyare so spaced as to provide four apertures or passages 14 which arelocated between the passages 12 and which are so arranged as to conductsealing liquid to the universal joint. As illustrated, the universaljoint is secured by means of a stud screw 15 and suitable nuts to theportion 13 of the pedestal.

In assembling the parts of the meter, the universal joint and the drummay be secured to the pedestal after the pedestal has been secured tothe casing 5. The gas passage 8 may then be secured to the casing andthe top of the casing may be secured in place. Any suitable means, suchas the aperture 16, may be provided for admitting sealing liquid intothe interior of the casing after the drum and the pedestal are in placeand the casing is sealed. The gas entering the inlet 7 flows upwardlythrough the pedestal passages and is delivered to the distributingchamber of the drum. From this chamber it is delivered to the successivemeasuring chambers of the drum by means of the valve 17. In theapparatus illustrated the valve 17 also controls the delivery of gasfrom the measuring chambers to the delivery champedestal is annularlydisposed nozhaving a gas passage 12, and
